Today I stumbled onto the best article I've ever read on the subject of heaven. It is short (you can finish reading the article in 15 mins but digesting it will take much longer), sweet (nothing offensive or disagreeable), simple (easy to understand layman's terms) and sensible (balanced teaching; no wild speculations or weird interpretations).
Of course, there is bound to be some speculation when discussing such a topic but whenever conjecture is called for, author Peter Kreeft is careful to give answers based on God's revelation of Himself and His ways. I like that.
So for answers to 35 frequently asked questions about heaven go to "What Will Heaven Be Like?"
Enjoy. I did.
